RELEASING-PENHOLDER.

Specification of Letters Patent.

Patented Ang. 7, 1917.

Application filed .Tune 11, 1915. Serial No. 33,555.

To @ZZ @IJ/iam t may concern:

Be it known that I, l/VALTER E. EDWARDS, a citizen of the United States,residing at Buena Park, in the county of Grange and State of California,have invented certain new and useful Improvements in Releasing-Penliolders, of which the following is .a specificati-on.

My invention relates to pen holders, and more particularly to animproved pen holder for receiving and clamping a pen, which is simple inconstruction, cheap to inanufacture, strong and durable, and quickly andeasily operated.

The primary object of my invention is to provide a pen holder of theclass above described having a clamping jaw pivotally mounted thereonfor engagement with a pen, suitable actuating means being provided formoving the clamping jaw into clamped position.

Another object of my invention is to provide a clamping jaw havingreinforcing means associated therewith adjacent the point at which theactuating means engages the same.

A further object of my invention is to provide a pen holder having theimproved clamping jaw formed of a. single sheet of bendable metal, andan improved releasing means associated therewith.

Vith the above and other objects in view my invention resides preferablyin the construction, combination, and arrangement of parts ashereinafter set forth in the specilication and illustrated in theaccompanying drawing, in which- Figure l is a longitudinal sectionalview of .a pen holding shank and handle embodying the improvements of myinvention.

Fig. 2 is a similar view showing a pen clamped therein.

Fig. 3 is a transverse sectional view taken on the line 3 3 of Fig. 2.

Fig. 4 is a plan view of the blank of bendable metal from which theclamping is formed.

Referring more particularly to the drawings in which the preferredembodiment of my invention is illustrated, I provide a pen holdingsleeve 1, which is preferably tubular and internally threaded as at 2adjacent one extremity. A handle 3 is provided having a threaded shank4, the free extremity of the threaded shank 4 being frusto-conical jawpreferably comprises a sheet 6 of bendable metal having one extremitythereof enlarged as indicated at 7 to provide a gripping jaw. rIhegripping portion or jaw 7 is preferably bent into arcuate shapetransversely so as to conform to the configuration of the tubularsleeve 1. The sheet G is provided, adjacent its opposite extremity, witha plurality of laterally extending ears S, said ears 8 having openings 9therein for a purpose which will hereinafter appear. The extremity ofthe sheet 6 adjacent the ears S is bent on the dotted line10 indicatedin F ig. l to provide an abutment 11 for a purpose which willhereinafter appear. The ears 8 are bent into the position shown in Fig.3 to provide reinforcing and bearing portions. As shown in Fig. 3, thebearing ears 8 are bent, as at 12, inwardly past the outer marginaledges of the abutments 11 so as to provide strengthening or reinforcingwalls performing their function in amanner which will hereinafterappear. The openings 9 are adapted to register and a transverse bolt,rivet, or the like 13 is receivable therethrough, the oppositeextremities of the rivet 13 being carried by the shank 1, `as shown atthe points 14 in Fig. 3. The sheet 6 is offset as at 15 substantiallyintermediate its length and adjacent the inner end of the clamping jaw 7to provide space between the inner wall of the tubular shank 1 and saidsheet to accommodate a fiat spring element 16 riveted or otherwisesecured, as at 17 to the sheet 6, and bent into yielding engagement asat 18 with the inner wall of the sleeve l. Attention is called to thefact that the spring 16 need not be riveted to the sheet 6, but may beformed integral therewith by striking a portion of the sheet outwardlyto provide a spring, this being within the scope of my invention andpossible of use when producing the same for practical use.

A pen is shown clamped in the holder in Fig. 2 and is designated 19, thepen being shown in dotted lines in Fig. l. When placing a pen in theholder, the handle 3 is slightly unscrewed from the shank 1. By thismovement the clamping jaw 7 will be moved to the position shown in Fig.1 by the action of the spring 16 and a pen may be inserted. By returningthe handle 3 tothe original position, the contacting portion 5 Willengage the abutment l1, causing the jaw to be moved into clampedengagement with the pen. It Will be noted that a comparatively smallcontact surface is presented by the conical end of the handle 3 againstthe abutment ll and that the -point or contact is offset from the pivot13. When pressure is exerted on the abutment 11, the reinforcingears orWalls S will very eectively perform the function of preventing bendingoi' the abutment when the pen is clamped. Particular attention is calledto the fact that when the invention is reduced to practical use, thereare only three component parts. These parts are the clamping member,holding shank, and the handle, the clamping member having the pivotears, spring, and clamping jaw formed integral.

While I have shown and described my invention as possessing a peculiarform and construction it is desired that it be understood that I maymake such changes in the details thereof that do not depart from thespirit and scope of the invention as claimed.

Having thus described my invention, what I claim `and desire to secureby Letters Patent, is:

A releasing pen holder, including a tubular holding sleeve having aninternally threaded extremity, a handle having a threaded end receivablein the threaded eX- tremity, a pen gripping member fulcrumed in thesleeve, said pen gripping member having a resilient gripping jaw and penguards formed therewith, a reinforced abutment on the gripping member,and a spring for urging the resilient jaW from engagement With thesleeve and the abutment into engagement with the threaded end oi thehandle.

In testimony whereof I aiiix my signature EDWARDS.'
